N-Alkyl(aryl)-3-amino-5H,6H,7H-pyrrolo[1,2-a]imidazole-2-carboxamides were obtained by the interaction of 5-alkyl(aryl)amino-2-(3-phthalimidopropyl)-1,3-oxazole-4-carbonitriles with hydrazine hydrate and have been used for the synthesis of substituted 3H,4H,6H,7H,8H-pyrrolo[2,1-h]purin-4-ones, their thione analogs, and also 1,2,3,6,7,8-hexahydro-4H-pyrrolo[2',1':2,3]imidazo[4,5-d]-[1,3,2]diazaphosphinine derivatives.
